Halx, when it dies does it go into a blue screen? How does it go down? Power's off / Locks-up / Speaker goes for a high pitched whinge / ???
If it goes into a blue screen, then it should* indicate the nature of the system failure (hardware/software).
Edit:
BTW - Why have you not upgraded to
XPSP2 ?
